two roamios one keeps losing wifi connection have to restart

Advertisements

I have two roamios that I purchase together. One is in the bedroom and one in our family room. Both work the same but the one in the bedroom keeps having to be restarted every day to get the wifi connection working. I have both Tivos using a 2.4 connection. The only other thing using that wifi is two laptops. One in the family room and my wife's in the bedroom. Both use the same wifi id.
Is there a firmware update that may be the one Tivo got and the other did not? Is this an indication that one of the Tivos is going bad? Connecting via ethernet cable is not an option unless for diagnostic purposes. Could my wife's laptop also running a 2.4 connection be causing a problem? She does not lose connection...just the Tivo. The bedroom Tivo is only about 8 ft away from the Access point. There are a couple of walls between the AP and the Tivo but that should not cause the problem when her laptop in the same room does not have a problem.
I was thinking of swapping Tivos to see if it followed the units. I could then say that it was the Tivo and not the environment.
Any ideas would be great.

 

I have 5g available on my AP. I have to have both tivos on the same speed/network so they can talk. Will try that but if that does not work then that idea of the electrical circuit connections is a good one. I use one of them for a connection to my solar adapter for seeing my panels and what they are doing. Works great.

 

I have one wifi called Bill which runs at 2.4 and the other one called Bill-5 which runs at 5.0 If one is on 2.4 and the other at 5 with those names they do not see each other.

 

I just changed my AP to do what they call smart selection for which speed is best. Both the 2.4 and 5 have the same SSID and security settings. Now the AP will decide which is best to use. All the devices presently are using 2.4. I did change the channel on the 2.4 to channel 4 just to see if that helps. Time will tell. What also is weird is that the one Tivo that is working fine shows it's name in the Attached Devices listing on the AP but the flaky one does not. It just shows unknown in place of the name. But both Tivos can see each other. ??? weird. I still think the one box needs a firmware blast!!

 

OK it was on 6 but you are right that 11 is least used. Made the change and the security I use is WPA2-PSK [AES] Seems plenty good for my environment.

 

Worked for a while but back to losing connection again. My laptop in the bedroom does not lose wifi connection. We have a smart tv and it sits right above on a shelf and never loses wifi connection. None of our other devices have this problem.
Is there a usb wifi adapter that can be connected to the Tivo to over ride the internal wifi adapter?

 

I am going to try a powerline adapter kit. I already have such a kit going from my solar dashboard device to my router and it works great. This will be on the same outlet at the router end but a different remote connection by the tivo. From everything I have read, you can have multiple powerline adapters. Then this Tivo will be wired. I just think this Tivo has a crappy wireless adapter inside and with the Roamio it will not take using a USB wireless adapter. I have several of those and they always work great on laptops. Why does Tivo make everything so difficult?

 

The two roamios were purchased at the same time. One has a 2t hhd and the other 500gig. I replaced the original 500g with the 2T drive since in the family room we record a lot of shows. The access point that is used for the wifi is about 8 ft away in another room. The family room Tivo is about 20 ft away from the AP. It never has a problem like the one in the bedroom. The way I get it back online is to reset the box. It used to work then for several days but now it only last about a few hours. Nothing has changed. The AP has both 2.4 and 5 hz running in a mode that allows the AP to use whichever is best. Right now both Tivos are set up to run 2.4. Other devices in the same area are all accessing the same AP and have no problems. That being said, it is logical that the Tivo has a problem internally with the wifi. A bridge is more money and the power adapters that I have used in the past are pretty solid. They sell for $37 on Amazon. I will see how that works next week. The Tivo box itself works fine otherwise. Question: Does the box have to communicate with a server at Tivo to perform some of its functions? Sometimes when we go to a show that we have recorded it will show the spinning circle like it is having trouble communicating. I always thought once it was recorded it was accessible instantly.
One other thing. Is the wifi adapter a chip that connects to the mainboard with a ribbon cable? I know that is how most laptops are built. I might just open this bad boy up and see if a reseating of the cables could fix this problem. We used to do that in the old days since most connectors are not gold-coated hence they get corroded over time. We always reseated 7 times and if that did not work then we knew the part was probably bad and had to be replaced. We also used to run into silver migration problems between the tracks on cables.
